Calculation design compression resistance N_Rd for column web

The design compression resistance N_Rd is given by  the minimum of the crushing resistance R_y,Rd, the crippling resistance R_a,Rd and the buckling resistance R_b,Rd of the column web (see Ref.[2], 5.7.3., 5.7.4., 5.7.5)

R_b,Rd is obtained by considering the web as a virtual compression member with an effective breadth b_eff and buckling length d.

tw	the column web thickness
ss	the plate height
bf	the column flange width
σf,Ed	the longitudinal stress in the flange
tf	the column flange thickness
d	the column web depth
a	distance to the nearer end of the member
h	the column height
